Ok, ok, i just made that up.
I got an Infrant ReadyNAS NV , before the company was bought up by NetGear. It's pretty awesome, though not perfect. Real hot-swappable RAID, dynamic reconfiguration, and lots of other good management tools. Looks pretty sweet, fairly quiet. Using it as a print server has always been problematic, tho.
Also, they seem to have gone up in price *quite* a bit. This site says the no-disk one is $1049. I think mine was around $600. I got one with no disks, and found a good deal on two 500GB disks (which were on their approved h/w list) and still ended up under $1200, and that was two or three years ago. But mine didn't have gigabit ethernet. I guess that explains some of the cost increase.
I set mine up with 500GB of storage, mirrored, and two open bays. I started offloading pix and video and backing up everything else, and a couple years later have not yet had to fill the other bays. But I like knowing I can expand to 1.5TB in RAID5 when I need the space.
